### Splitting of Quasi-Definite Linear System Maintains Inertia

**Authors:** Martin Neuenhofen

**Comments:** 4 Pages.

We show that there is a variety of Schur complements that yield a decoupling of a quasi-definite linear system into two quasi-definite linear systems of half the size each. Splitting of linear systems of equations via Schur complements is widely used to reduce the size of a linear system of equations. Quasi-definite linear systems arise in a variety of computational engineering applications.
